Nutrient enrichment effect on macroinvertebrates in a lowland stream of Argentina Iheringia, Sér. Zool.
Cortelezzi,Agustina; Ocón,Carolina; Oosterom,María V. López van; Cepeda,Rosana; Capítulo,Alberto Rodrigues.
ABSTRACT One of the most important effects derived from the intensive land use is the increase of nutrient concentration in the aquatic systems due to superficial drainage. Besides, the increment of precipitations in South America connected to the global climate change could intensify these anthropic impacts due to the changes in the runoff pattern and a greater discharge of water in the streams and rivers. The pampean streams are singular environments with high natural nutrient concentrations which could be increased even more if the predictions of global climate change for the area are met. In this context, the effect of experimental nutrient addition on macroinvertebrates in a lowland stream is studied. Samplings were carried out from March 2007 to...
